UN resolution 242 which anti-Israelis like to quote so much, does NOT demand Israel's withdrawal from the '67 occupied territories, UNLESS IT IS A PART OF A FINAL PEACE TREATY IN WHICH THE ARABS WOULD ACCEPT ISRAEL'S RIGHT TO EXIST AND STOP TRYING TO DESTROY HER. So far those states that did just that, Egypt and Jordan got just that. The Palestinians have been playing dirty games even when they "claimed" they recognize Israel's right to exist. They have NEVER made a serious effort to show Israelis that they really mean business.
